Straightforward like-for-like roof repairs are often different from changing the shape, height or visible character of a roof. The safest approach is to check the specific property and proposal rather than assume every roof job falls under the same rule.
Crawley has conservation areas
Crawley Borough Council currently identifies 13 conservation areas and explains that some permitted development rights can be more restricted within them. That matters if work changes the external appearance rather than simply repairing a defect.
Listed buildings are a separate question
A listed building can require listed building consent for works that affect its special architectural or historic interest. Do not treat a listed roof as an ordinary like-for-like replacement without checking first.
Building regulations may still matter
Planning permission and building regulations are separate systems. Reroofing, structural changes and thermal upgrades can trigger building-regulation considerations even when planning permission is not required.
Check before ordering materials
If the property is listed, in a conservation area, or the work changes roof shape, height, materials or visible features, checking with the relevant authority before committing to the specification can prevent expensive rework.
